Be it known that I, ALFRED A. D Ei INis, a citizen of the United States, 'lc sldlng at -Grand Rapids, county of, Kent, State of Michigan, haveinvented certain new and; useful, Improvements in Vehicle-Signals, I I p of. 'iThese partsare shown conventionally and are illustrated to show the application of which the* following i s' a specification This invention relates to improvementsfin vehicle signals.

The mainob'jects of this "invention are: 1 First, to provide an improved signal for motor vehicles whicligis easily installed upon 3 a vehicle either as an attachment or 7 em bodied in a structure during manufacture! Second, to provide an improved motor 1 vehicle signal which-isvery easy to o'perate' V i I v y g g I I at 7 'wh1lethes1gnal member 5' ispivoted and also positive in its operation:

Further objects, and objects relating'to structural details, will? definitely appear from the detailed description to follow; I accomplish the objects of my invention y h ,d o sand me n de i ib d i the following specification. The invention is having my improvements embodied therein,

parts of the vehicle body being broken away to show structural details, the parts being mainly shown conventionally.

Fig. II is an outer side elevation of the rear signal of the embodiment of Fig. I, the rear fender being shown in section.

Fig. III is a front view or view looking from the left of Fig. II, with a portion of the housing removed, one of the signal arms being shown in its actuated position by dotted lines.

Fig. IV is a detail view on a line corresponding to line 44: of Figs. I and V, showing the arrangement of the control valves.

Fig. V is a detail section on a line corresponding to line 55 of Fig. IV.

Fig. VI is a detail view of the parts shown in Fig. II looking from the left with front signal member and its housing or support removed.

Fig. VII is a cross section through one acters refer to similar parts throughout the s eificafidn ofLettersPatent. ,Patented Jan. 4, 1921. Application filed Apri1'8, 1919. sem irolzsaeia v taken looking in the'direction of the little arrows at'the endsof'the section lines.

several views, andthe sectional views are "Referringto the drawing, 1 represents theybodyof a motor. vehiclefi an internal combustlon motor, and 8 the manifold there or adaptationfof my improvements. l The signal members may be mounted on any part-10f thevehicle desired; In" the "structure illustrated I have shown them mounted on the front and rear left side feni ders, there being apair of signal members 4; and 5at the rearmounted in a housing or supportb. The signal member 4: is pivoted at "8 within the l1ousing,1there being 'a parti-v tion 9 dividingfthe' housing into com are i ments for-thesignal members. Each signal member is provided withan actuating plun-' ger 10, the cylinders 11' and 12of which are connected by-the pipes 13 and 14 tothe I valve casing 1,5.1 Thisyvalve casing is in I so turn connected to themanifoldby the pipe 16.'..:IThe"pipes or' conduits 13 and 14 are P 1 controlled by the valves 17 and 18 respectively, the manifold conduit lfibeing connected to the valve casing between these valves 17 and 18 as shown in Figs. IV and V.

, vThevalve 17 is provided with an operat-' ing rod 119 mounted on the steering post 20 so as to be operated by the knee of the driver, the rod having a crank-like offset 21 g, W

therein,-see Fig. 1.1

The valve 18 is. connected by the link 22 I to the brakerod '28 or some other portion of the brake mechanism so that when the brake is actuated to stop the vehicle the cylinder 12 is connected to the manifold: and suction actuates the arm or signal member 5which A single signal member 25 is mounted on the front left fender, it being provided with a cylinder and plunger, the same as i described, connected by the pipe26 to the pipe 13, sothatboth the frontandrearfsi nal members are actuated when the valve 1 opened.

The plungers are connected tothe signal Y members by means of the flexible cables 27 100 I so that the suction draws downthe plungerf Y arranged over eccentrics 28 on the signal member pivots.

To prevent water and dust working into the cylinders the 'plungers have housing sleeves 29 secured thereto to embrace the upper ends of the cylinders.

To attract attention to the signal mechanism 1 preferably provide the rear housing with a lamp 30 which may serve as a tail lamp for the vehicle, the housing being provided with a lens 31 opposite the lamp;

The si ial members have a'series of holes 32 alinec with the lamp when the signal members are in their normal position. The signal members may be otherwise formed to permit thepassage of the light. 4

To. further attract attention to the signal 1, preferably mount a small lamp 38-at the outer end of the signal member, the same. being connected by the wires 34 to the wiring for the lamp SO, so that they may be con tinuously lighted.

My improved signal devicemay be readily installed as'anattachmentor built into a motor vehicle in the manufacture thereof. I have illustrated anddescribed the same mainly in conventional form as structural details may be I greatly varied, also 'the adaptation thereof to the vehicle.

I have not attempted to-illustr'ate or describe various modifications and adaptations as believe the disclosuremade will enable those skilledin the'artto which-my invention relates to embody or'adapt the same as may be desired.

Having thus described my invention, what I claim as new'and desire to secure by Letters Patent, is:

1. In a motor vehicle including a body, an internal combustion motor and an intake manifold therefor, the combination of a pivotally mounted signal member carried by said body, an eccentric on the pivot of said signal member, an actuating plunger for said signal member, a flexible connection for said eccentric'to said plunger, a cylinder for said plunger, a housingsleeveslidably embracing said cylinder and secured to the plunger, said housing sleeve constituting a guide'for the plunger and a shield for the cylinder, a conduit connecting said cylinder to said manifold, and a control valve for said conduit whereby when "the valve is opened the signal member isactuated'by suction.

2. Thecombination with an internal combustion engine, of ail-intakepipe-therefor, a movable signal member, a signal. actuating plunger connected to said signal memberga cylinder therefor connected to; said -intake pipe, and a housing sleeveslidably ernbrao ing the upperend of thecyl-inder andsecured to the plunger, for the purpose specified. p

In witness whereof 'I haveh'ereunto set my hand and seal in the'presence of two witnesses.
